Parasitoides or natural enemies are beneficial insects that lives on the host pest and finally kill the pest and the parasitoides emerge as a adult to control the further pest in the crop. Parasitoides are non-vegetarian insects and will not disturb the plants and attack only the pest. Parasitoides are naturally present in the eco system and because of use of chemical pesticides these parasitoides are lost. So we are forced to introduce them in the eco system to balance the lost equilibrium.
Bracon brevicornis is highly polyphagous, gregarious, and ecto-larval parasitoids attack the larval stages of Moths and Butterfly. Some of the common pest attached by Bracon are Coconut black headed caterpillar (Opisina arenosella), Angoumois grain moth (Sitotroga cerealella), Wax moth (Galleria mellonella), Indian meal moth (Plodia interpunctella), Castor shoot and capsule borer (Conogethes punctiferalis), castor semilooper (Achaea janata), Cabbage head borer (Hellula undalis), Gram pod borer (Helicoverpa armigera, Spotted pod borer (Maruca testulalis), Spotted bollworm (Earias vittella), Tobacco caterpillar (Spodoptera litura), Cabbage leaf webber (Crocidolomia binotalis), Sorghum/maize stem borer (Chilo partellus), and Pink bollworm (Pectinophora gossypiella)
Bracon can be released in two ways either Stapling Bracon card with pupae under the leaf or releasing bracon adults directly in the field. The adult will fly out and search for the pest larvae to parasitize the eggs
